Development of next generation energy and environmental business
As the world becomes increasingly conscious of global environmental issues, we are also becoming actively involved in environmentally-friendly business with the aim of realizing a low carbon society. By organically linking our diverse functions as a sogo shosha (general trading company), we pursue the development of projects that help prevent global warming. We are also proceeding with environmental and next-generation energy business including the commercialization of renewable energies such as biofuel, development of next-generation energy sources, and development of a hydrogen transportation and storage model.
